Shorty 40 dipole
SpletThe performance is pretty much dipole-like on 40m and 20m. The higher bands were closed at the time. Extensive tests with WSPR on 80m showed it was about 8.5-12dB (perhaps 2 S points) down on a W5GI dipole at the same height. While this is not a big performer on 80m it will get you on a band that you might otherwise not have access to. Splet02. maj 2024 · A Simple Homebrew Hamstick Dipole. ... There are three foot long "shorty" hamsticks that are much less efficient than the 8 foot version. For the higher HF bands hamsticks are still fairly efficient. In fact on 10 meters the eight foot hamsticks are barely shortened. A full length 15 meter quarter-wave is about 11 feet, so a hamstick is about 8 ...

Splet05. avg. 2016 · Nominal dimensions of the G3YCC and KJ5VW dipoles The G3YCC "shorty" dipole is made of aluminium tubing, whereas the KJ5VW model is a wire-dipole. Both are "half size" dipoles. Scaling-down an full-size antenna by more than 50% causes significant performance reductions. SpletDescription.

SpletI have used the "Shorty" on bands from 10 through 160 - It was impossible to tune on 160 as it came in the packaging, but a simple modification was all it took. Ditching the ladder line completely, and using a 9:1 balun as the dipole center, feeding with RG213, not only does the 40m issue go away, but it "flattens" the VSWR curve some.

SpletWith the dipole, my background noise level is about S 4 to S 5, rising to S 6 when the noise sources are on. ... It works from 160 to 40, so it can be used for reception on a number of bands. The advantage of the terminated loop over usual small loops is that the antenna has nulls to the side and a null to the back.
